bug #13222 has been closed, but during the discussion it was stated that evdev-1.1.x versions are not compatible with xserver-1.4 (the latest official version is 1.1.5).
I suggest coordinating the release of a new evdev driver with xserver-1.4.1 and also adding a small note on the release notes about it.
BTW, I also have a new suggestion for a fix before 1.4.1: bug #13246

sorry, but i'm not merging 12439. if eric, adam or keith wants to prepare a full list of quirks to backport _from master_ then that's fine, but i'd rather not use code that hasn't even hit master, much less taking one fix instead of all of them.
